A 10-year-old boy is found by emergency workers after a car crash, crying loudly with contusions to both legs, weakness abducting the right arm without swelling, and vital signs normal for his age. He states that his arm and shoulder were pulled backward in the seat belt during the crash. Which of the following trauma emergency priority does this patient belong to?
Below the acromion lies the acromial bursa, which is a small sac filled with rubbery synovial fluid, that provides lubrication and prevents the rotator cuff tendons, especially the supraspinatus tendon, from rubbing against the acromion as the joint moves.
Now, the tears may be partial, which is where the tendon is damaged but not completely torn, and may even go unnoticed.
In contrast to an acute tear, there may also be a chronic tear due to regular wear and tear, which usually occurs in the elderly.
That’s because the blood supply to the rotator cuff tendons reduces over time making it harder for them to heal after an injury.
